Coastal geomorphological changes in the short-term and long-term are observable in all coastal areas. The changes occur to reach the balance in this region. Aware of these changes is very important to geomorphologists, environmental planners to help them to solve coastal problems. The purpose of this study is to assess the geomorphologic changes occurring in the region of coastal Bushehr Port Kangan place within the Ziarat estuary. In this study multi-temporal satellite images of Landsat were selected as the data base. The principal component analysis and fuzzy logic are used for monitoring and evaluating the geomorphological changes. Results of this research show that during the 21 year research period from 1986 to 2006 most important factor changing landforms and coastline in the region are changes water level of the Persian Gulf that cause to submerged about 46 square kilometers of the region's coastal zone land. The important part of this area is containing spits and low slope and delta. The result of this research can be used for infrastructure projects, port facilities, commercial and military activities.

Sarbisheh area is located in the west of Sarbisheh and southeast of Birjand, South Khorasan province. This area is located in the Birjand ophiolite melange zone and is a part of the northern part of the Iranshahr-Birjand metallogenic belt. The lithological units in this area include ophiolite melange, flysch facies sediments, pyroclastic rocks and Quaternary sediments. Geochemical studies of stream sediments and identification of geochemical indicators of mineral resources in the region were performed using the results of geochemical analysis and principal component analysis. Remote sensing studies were performed on the ASTER and Landsat satellite images using color composite, selective principal component analysis (crusta) on the Landsat 8 satellite imagery to identify the alteration zones. The lineaments of the region were drawn using the high-pass filter method of the ASTER satellite image and the Google image. Finally, by creating layers of geological units, geochemical data, alteration and lineament and integrating them with fuzzy method, areas with potential mineralization of nickel, chromium, cobalt, copper, lead, zinc and magnesite were identified.
